Least well-known threat to urban dogs in the winter

IMPORTANT UPDATE: Another dog dies this winter.

Many of you may remember the woman who died walking her dogs last year from an electrified manhole cover. Yes, it does happen. In the winter, salt applied to ice-covered streets corrodes electrical wires, causing manhole covers and sometimes lamposts to have stray voltage. If your dog suddenly stops, bolts, or yelps, he or she may be experiencing a painful shock. Last year a dog was killed in Park Slope, so it is a concern. Here are some tips to keep your pooch safe.

1. Be safe, not sorry. If your dog hates to go down certain streets or near a particular lampost, listen to him. He may have experienced a shock in the past.

2. If possible, you and your pet should wear rubber-soled shoes in winter.

3. Try to avoid manhole covers and try not to let your dog urinate on lamposts. There are always trees and fire hydrants.

4. If your dog does show signs of electrocution, do not touch him, no matter how hard it is not to. You'll only put yourself in danger.

5. If you suspect stray voltage, call Con Edison 800-75-CONED or New York City at 311. In the case of emergency, always call 911.
